"My cat drinks out of a glass on my nightstand rather than a bowl. a couple of years ago, she was having some pretty serious dental issues (all fixed now), and was being reluctant to eat and drink. she had always wanted to drink out of the water cup i had for myself, and at that point i just wanted her to drink anything, so i let her.
that was my mistake and now she refuses to drink out of a bowl on the ground, and will only drink out of cups. she has a permanent cup on my nightstand, to this day. oh well, at least it’s easier for me to monitor her water intake."
